Abstract: 876,825. Fluid actuation of switches; thermal switches. KAISER, J., and MAYER, F. July 3, 1959, No. 23004/59. Class 38 (5). [Also in Groups XI and XIII] An electric flow heater (see Group XI) is provided with a switching mechanism actuated by pressure- and temperature-sensitive control members for energizing and de-energizing the heating coils. As shown in Fig. 1, when the liquid pressure is sufficiently high on the inlet side, diaphragm 35 urges lever 30 upwardly to close contacts 31. However, when the pressure on the outlet side is too high or when overheating occurs, diaphragm 36 or a temperature-responsive control member (see Group XIII) urges the insulating bridge 33 upwardly to reopen the contacts. In a further embodiment the heater has two heating systems connected to contacts 58, 60, Fig. 7. A diaphragm of maximum pressure-response operates lever arm 57, Fig. 7, to close contacts 58 and diaphragm 48 of lower pressure response operates lever 61 to close contacts 60, while a common de-energizing diaphragm 59 of minimum pressure response first opens contacts 58 and only thereafter, under further pressure, opens contacts 60. In the arrangement shown in Fig. 19 a double-acting diaphragm 153 is used, the lower side being in contact with inflowing liquid and the upper side with outflowing liquid, the contacts 158 being closed only when the pressure difference exceeds a predetermined value. Contacts 173, which are normally closed, may be opened by a temperature-control diaphragm 169. In order to ensure sudden contact operation the movable contacts may be provided with magnetic armatures, a permanent magnet being arranged in the path of movement thereof.

Abstract: The invention comprises pregnane-5a ,11b ,-17a ,21-tetrol-3,20-dione and the 21-acetate thereof, and the 3,20-bisethylene ketal derivatives of both compounds, and a process for producing pregnane compounds by reducing D 5 - pregnene - 11b ,17a ,21 - triol - 3,20 - dione - 5a ,6a  - oxide 21-lower fatty acid ester 3,20-bis-lower alkylene ketal in an inert organic solvent, e.g. tetrahydrofuran, with lithium aluminium hydride to form a pregnane-5a ,11b ,17a ,21-tetrol -3,20 - dione 3,20 - bis - lower alkylene ketal, and, if desired, hydrolysing with acid said ketal to produce pregnane-5a ,11b ,17b ,21-tetrol-3,20-dione.  The above process may be modified in that the D 5-pregnene-11b ,17a ,21-triol-3,20-bis -lower alkylene ketal is prepared from a bis-lower alkylene ketal of a hydrocortisone lower fatty acid ester by reaction with an organic per-acid.  The lower fatty acid acyl radicals and the lower alkylene ketal radicals contain 1 to 4 carbon atoms, suitable acyl radicals being acetyl, propionyl and butyryl radicals and suitable alkelene radicals being ethylene ketal, propylene ketal and methylpropylene radicals.  The reaction with the organic peracid may be carried out with perbenzoic or monoperphthalic acid at room temperature in an inert organic solvent such as chloroform, carbon tetrachloride or ethyl acetate, to form a mixture of the 5a ,6a -oxide and 5b ,6b -oxide which may be resolved by chromatography or used as a mixture for the following reduction step with lithium aluminium hydride.  In the examples pregnane-11b ,17a ,21-triol - 3,20 - dione - 5a ,6a  - oxide 21 - acetate-3,20-bisethylene ketal and the corresponding 5b ,6b -oxide are prepared.  The mixture of oxides or the 5a ,6a -oxide are reduced with lithium aluminium hydride to form pregnane-5a ,11b ,17a ,21 - tetrol - 3,20 - dione 3,20 - bis-ethylene ketal which is acetylated to form the corresponding 21-acetate, or treated with sulphuric acid to form pregnane-5a ,11b ,17a ,21-tetrol-3,20-dione which is acetylated to form the corresponding 21-acetate.  The pregnane-5a ,-11b ,17a ,21 - tetrol - 3,20 - dione 3,20 - bis-ethylene ketal 21-acetate is also saponified with alcoholic potassium hydroxide to form the corresponding 21-hydroxy compound.
